Specification forming part of Letters atent No. 19, [25, dated January 19, 1858.

Be it known that we, SAML. R. BoRUM and VWILLIAM MCCLEAVN, ot Norfolk, in thecoun'ty of Norfolk and State of-Virginia, hate invented a new and useful Improvement in the C'onstruction of 4`Donble-Mold-Board Plowsy and we doherebydeelare that the following is a full,elear,fand exact'description of the saine,

reference being had 'to the annexedfdrawings,

I making' a part of this specification, in whichy .,Fignre l.-is a longitudinal vertical section of'our improvement, taken in theline zr, Fig.

` 2. "Fig, 2 is 'also alseet'ion` of the same', taken on the planeofthe boltnhich 'connects the standard 'with landside, asindicated -fbythe This invention'cousistsinthe peculiar forma! the standard,as'hereinafter set'tbrth."

`tion and combination of' the mold-board 'and lTo enable those-'skilledA inlthe' art tof-ully' understandvand constructeur invention', we'

will proceed to describe it.

A represents the-beam ol' the plow, the'baok end ot' which isbolted to handles'tl, the lower .ends ofthe two handles extending downward :to the back end of the'landside, and beingsecured thereto by a bolt, a. The upper ends of the handles() are of-the'usnal curvcdform, as plainly shown in.v Fig. 1. The landside' C is con'structed'of cast-iron, and its front end has an uprightbar or projection, b, formed on it, the bar' and landside being cast in one piece. The outside of the projection b is .rounded .transverselyand curved longitudinally.

I) represents a standard, which transversely is of V form. yThis standard gradually'ex- -pands from its upper toits lower end, so as to form mold-boards, and shares care attached to the lower ends of the mold-boards-on'eto each.

' Thestandard is constructed of cast-iron, and its upper epd is securedto the beam A by a.

`bolt, d,'as plainly shown in Fig. 1.

The upright bar or projection b corresponds in form .with the internal angle of the 'standard,as shown clearly in Fig. 2, and t'he bar or projection is fitted snugly within it, und the projection is firmly secured to the standard by .a screw-bolt, e, as shown in 4both figures.

By having the standard constructed as shown, and the landside provided with the bar or projection b tted -in the angle of the standard, and the standard andbarbolted together,

as shown, a very strong and durable imple- `ment is obtained.

The dificulty attending the use of plows of this description is that they are not durable. The shares .are liable tobreak', and the moldboards often become loose, andthe im plemeixt soonrendered worthless in consequence ofthe diiculty of properly supporting the parts. By.

our improvement this diiiculty is'obviated. The bar b zti'ords a rmsupportforthe standard and mold-boards. A wing or pulverizer,`

- B', passes transversely through -the landside- O, and issecured therein by means ot' pinsf.

'(See .more particularly Fig-2..)

' -A patent was formerly gran-ted 'to F. E.

Richardson for a doublennold-board plow -in which aring or hand wasused for connecting the landside with the standard.` These imple-- ments, however, are' notdurable. The. moldboards frequently break, and the implement generally is not so str'ong and d urableJas -t-he one herein described. n our improvement the landside C is cast in a separate piece from the standard D., and the said standard serves also the purpose of a mold-board. This method possesses very evident advantages, in regard to economy, over the plan of casting the land-- side and moldlboardjnone piece. In the latter case, if the farmer breaks the. landside,the

mold-board is also rendered useless and must be replaced.

'We do not claim the invention of double mold-boards, for we know they are old; but

to the best of our knowledge' and belief it is4 new to make the standard transversely of V shaped form, gradually. expanding from the upper to the lower part, the said peculiarly-- shaped standard being combined with the horn or projection 'b ot' the landside C', in the nian ner herein'set forth. Therefore *What we claim as our invention, and desire to secure by Letters Patent, is-

- The arrangement ot' the peculiarly-formed -V-shapedstand-.1rd Dwith the horn or projection b ot the landside C and its wingsB, as herein shown and described'.
